int main(void)

{

static u8 key_state=1;

Stm32_Clock_Init(9);

delay_init(72);

Adda_Init();

while(1)

{

if(KEY0==0&&key_state)

{

delay_ms(10);

key_state=0;

ADC1->CR2|=1<<22;

LED1=!LED1;

}

if(KEY0==1)

key_state=1;

}

}

程序的目的是ADC1通道0单次采集，按一次按键采集一次，采集完产生EOC中断，在中断中LED0翻转，while中LED1翻转。现在问题是如果不使用MY_NVIC_Init进行中断分组，LED1可以根据按键翻转，LED0无现象，但是进行MY_NVIC_Init中断分组后，LED0没有任何现象，也就是没有进入中断吧，程序哪里有问题吗？

ADC1_2_IRQHandler

void ADC1_2_IRQHandler(void)
{
if(ADC1->SR&1<<1)
{
LED0=!LED0;
ADC1->SR&=0X2;
}

 ADC_IRQHanlder好像是STM32F4里面这样写的，不知道新文件是不是也是这么写
